Some of the current main research areas involving techniques related to XML consist of storing XML documents, optimizing the query, and indexing. As such we may focus on the set of documents that are composed of various structures, but that are not shared with common structure such as the same DTD or XML Schema. In the case, it is essential to analyze structural similarities and differences among many documents. For example, when the documents from the Web or EDMS (Electronic Document Management System) are required to be merged or classified, it is very important to find the common structure for the process of handling documents. In this paper, we transformed sequential pattern mining algorithms(1) to extract maximal similar paths between two XML documents. Experiments with XML documents show that our transformed sequential pattern mining algorithms can exactly find common structures and maximal similar paths between them. For analyzing experimental results, similarity metrics based on maximal similar paths can exactly classify the types of XML documents.

This study is attempt to develop for Korean traditional food data integration system with food database. We are collected all kinds of traditional Korean foods, and referred to document and classified according to food types and cooking methods. Also we are classified 6 types of traditional Korean foods as follows: traditional common, royal, local, festival, rites, and Buddhist temple foods, And we integrate all of that databases for using a specialist or not. We researched for Korean traditional food by cooking type and planed organization for the standardized code and construction for database of Korean traditional foods. It was combined all of them, constructed for Korean traditional food data integration system. Korean traditional foods are classified with 10 provinces local foods, 18 festival foods by seasonal divisions reflecting traditional Korean holidays; and 9 classes rites foods. Korean traditional food using a traditional Korean food classification system was investigated a total of 7,289 kinds foods according to food types. those were 2,585 kinds traditional common foods, 142 kinds of royal foods, 2,137 kinds of local foods, 515 kinds of festival foods, 403 kinds of rites foods, and 1,507 kinds of Buddhist temple foods. And Korean traditional foods included 980 kinds of main dishes, 4,456 kinds of side dishes, 873 kinds of tteok lyou, 515 kinds of hangwa lyou and 465 kinds of emchong lyou. It is therefore recommended that knowledge of traditional Korean foods be preserving and develop their excellence and to further studies.

This study investigated the relationship between inner characteristics manifested through the characteristics of artistic styles and formativeness manifested through external expressions of architectural styles in the early Medieval Period and early Renaissance Period. The method applied to this study is as follows. First, a historical document research was conducted centering on academic theses, related books, and academic databases; in addition, a case study identified the aesthetic characteristics of women's clothes. The conclusion of this study is as follows. First, the following is the analysis of the relationship between the artistic mode and architectural formativeness in the early Medieval Period and early Renaissance Period that represent a turning point in artistic paradigms. Second, the inner characteristics and eclecticism of the artistic mode literally appear in the formativeness of architectural style in the early Medieval Period, and the eclecticism in the architectural style appears to be expressed through a combination with new styles based on the application of the retro mode such as the eclectic adoption of cultural styles of various regions based on the tradition and technology of ancient Rome. Third, the trend of the aesthetic characteristics commonly appear in the modern style of expression related to the aesthetic characteristics of western women's clothes in the early Medieval Period; in addition, the early Renaissance Period was analyzed as decorativeness and respectively manipulability.

Objectives : The objective of this review was to evaluate clinical trials of warming acupuncture for musculoskeletal pain diseases, to assess the methodologic quality of the trials and determine whether low-quality trials are associated with positive outcomes, to document adverse effects and to identify the effectiveness of the warming acupuncture. Methods : Seven databases and the Journal ZHONGGUO ZHENJIU(中國鍼灸) published between 2004－2008 were searched. Korean and Chinese randomized trials were evaluated for methodologic quality using the modified Jadad scale. Outcome measurements were pain, function and global improvement. The best-evidence synthesis was performed to determine the strength of evidence by control group. Results : Six clinical trials representing 564 patients with musculoskeletal pain diseases were identified. For pain and function, there was moderate evidence that warming acupuncture is more effective than manual acupuncture. For patient global assesment, there was limited evidence that warming acupuncture is more effective than manual acupuncture. However, for function, there was inconclusive evidence that warming acupuncture is more effective than acupuncture with TDP or western medicine or acupoint-injection treatment. Conclusions : The evidence suggests that warming acupuncture is more effective for musculoskeletal pain diseases than manual acupuncture, acupuncture with TDP, western medicine and acupoint-injection treatment. But the evidence is moderate to inclusive due to the low methodologic quality of the trials. Further clinical trials with high methodologic quality is required to investigate the effectiveness of warming acupuncture.

Recently, because of the extensive use of geographic information in the various fields, the requirement for the easy circulation and utilization of the various geographic information among the individuals, organizations, societies and countries is raised. In order to support the interoperability of the heterogeneous geographic information in the various fields, OGC(Open GIS Consortium) proposed the GML(Geography Markup Language) specification that defines the XML encoding rule about the heterogeneous geographic information. In addition, ISO/TC 211 adopted the GML specification to make it as the international standard. Therefore, in this paper we first analyzed the GML 3.0 specification in detail that can support the interoperability of the heterogeneous geographic information. And then we suggested and applied the mapping rule that define the encoding method to improve the encoding process easily and efficiently. Finally we designed and implemented the GML 3.0 encoding system using the mapping rule to encode the geographic information that was constructed in spatial databases into the GML 3.0 document. Especially, we used ZEUS as a spatial database system to test our encoding system in this paper.

To improve the international competitiveness of research and academic libraries in Korea, it is essential to review the total amount of domestic information resources in comparison with those of other advanced countries, and then to make their best use. In this study, an attempt is made to estimate the annual budget for collecting foreign knowledge information resources spent by academic and research libraries in Korea. This budget estimate could be used for a basis for setting up the appropriate collection size and the efficient channel for distributing and sharing information resources among academic and research libraries on the governmental level. The total budget for collecting foreign knowledge information resources, including foreign monographs and scholarly journals in print, and the budget for foreign electronic journals, and web databases were estimated for academic libraries and research libraries, respectively, while the budget for international document delivery services was estimated without distinction between the types of libraries.

Current studies on storing XML data are focused on either mapping XML data to existing RDBMS efficiently or developing a native XML storage. Some native XML storages store each XML node with parsed object form. Clustering, the physical arrangement of each object, can be an important factor to increase the performance with this storing method. In this paper, we propose re-clustering techniques that can store an XML document efficiently. Proposed clustering technique uses path similarities among data nodes, which can reduce page I/Os when returning query results. And proposed technique can process a path query only using small number of clusters as possible instead of using all clusters. This enables efficient processing of path query because we can reduce search space by skipping unnecessary data. Finally, we apply existing clustering techniques to store XML data and compare the performance with proposed technique. Our results show that the performance of XML storage can be improved by using a proper clustering technique.

XML can describe a wide range of data, from regular to irregular and from flat to deeply nested. Thus, XML is rapidly emerging as the do facto standard for the Web document format since XML supports an efficient data exchange and integration. Also, to retrieve the data represented by XML, several XML query languages are proposed. XML query languages such as XPath and XQuery use path expressions to traverse irregularly structured data which comprise B% elements. To evaluate path expressions, various path indexes are proposed. However, traditional path indexes are constructed by utilizing only the XML data structure. Therefore, in this paper, we propose an adaptive path index which utilizes the XML data structure as well as query workloads. To improve the query performance, the adaptive path index proposed by this paper manages the frequently used paths and the structural summary of the XML data using a hash tree and a graph structure. Experimental results show that the adaptive path index improves the query performance typically 2 to 69 times compared with the existing indexes.

Search results of XML keyword search are defined generally as the most specific elements containing all query keywords in the literature. The labels of XML elements and semantic information such as ontology, conceptual model, thesaurus, and so on, are used to improve the preciseness of the search results. This paper presents a hierarchical index for an efficient XML keyword query processing on the condition that returnable search concepts are defined and users' query concepts can be interpreted with the help of the semantic information. The hierarchical index separately stores the XML elements containing a keyword on the basis of the hierarchical relations of the concepts that the XML elements belong to, and makes it possible to obtain least common ancestors, which are candidates for the search results, with selectively reading the elements belonging to the concepts relevant to query concepts and without considering all the combinations of the elements having been read. This paper deals with how to organize the hierarchical index and how to process XML keyword queries with the index. In our experiment with the DBLP XML document and the XML documents in the INEX2003 test set, the hierarchical index worked well.
